.SH NAME
CLAG2Z - a COMPLEX SINGLE PRECISION matrix, SA, to a COMPLEX DOUBLE PRECISION matrix, A
.SH SYNOPSIS

.SH PURPOSE
CLAG2Z converts a COMPLEX SINGLE PRECISION matrix, SA, to a COMPLEX
DOUBLE PRECISION matrix, A.

Note that while it is possible to overflow while converting 
from double to single, it is not possible to overflow when
converting from single to double. 
.br

This is a helper routine so there is no argument checking.

.SH ARGUMENTS
.TP 8
M       (input) INTEGER
The number of lines of the matrix A.  M >= 0.
.TP 8
N       (input) INTEGER
The number of columns of the matrix A.  N >= 0.
.TP 8
SA      (output) REAL array, dimension (LDSA,N)
On exit, the M-by-N coefficient matrix SA.
.TP 8
LDSA    (input) INTEGER
The leading dimension of the array SA.  LDSA >= max(1,M).
.TP 8
A       (input) DOUBLE PRECISION array, dimension (LDA,N)
On entry, the M-by-N coefficient matrix A.
.TP 8
LDA     (input) INTEGER
The leading dimension of the array A.  LDA >= max(1,M).
.TP 8
INFO    (output) INTEGER
= 0:  successful exit
